Troubleshooting

VMs can't receive tasks anymore

If for some reason VM appear to not receive tasks, this's because it's not reachable anymore.
Reloading your browser will show the VM as state <unreachable> in the ovirt UI.
At first, check that hosts are still available. If so, you gonna have to do a manual reload of ovirt taksOmatic on the broker connectivity.

Log in to capp1 and restart services in this order (hold few sec for each)

sudo service ovirt-taskomatic restart

Cnodes or VM are unreachable

If cnode(s) or VM got unreachable, there're a couple of way to figure out what's going on.

If there're not :

sudo libvirtd-qpid start
sudo libvirtd start

3. If both cnode and VM are still UP and running, it could be a timeout on qmf connectivity or db-omatic died without any reason. The best way to fix this is to reload ovirt qmf/qpid's process as follow :
